The Rolex GMT-Master II reference 126713GRNR-0001, often nicknamed the Zombie, is a sophisticated travel watch that reintroduced yellow gold and steel combinations to the collection in 2023. It features a 40mm Oyster case crafted from Yellow Rolesor, a signature blend of 904L Oystersteel and 18k yellow gold. This model is distinguished by its bidirectional rotatable bezel fitted with a two-color Cerachrom insert in grey and black ceramic, representing day and night hours. The black dial provides high legibility through a Chromalight display with gold-applied hour markers and hands. It is paired exclusively with a five-link Jubilee bracelet, marking the first time this supple, comfortable bracelet style has been offered on a precious metal GMT-Master II.
The timepiece is powered by the in-house Calibre 3285, a self-winding mechanical movement that offers a power reserve of approximately 70 hours and a precision of -2/+2 seconds per day. Its primary complication is the GMT function, which utilizes a dedicated 24-hour hand and a rotatable bezel to track multiple time zones simultaneously. The independent jumping hour hand allows travelers to easily adjust local time without affecting the accuracy of the seconds or the 24-hour hand. Additional features include an instantaneous date display at 3 o’clock magnified by a Cyclops lens, a Triplock screw-down crown for water resistance up to 100 meters, and an Oysterlock safety clasp with a 5mm Easylink extension.
General reviews of the 126713GRNR highlight its successful balance of luxury and functionality, noting that the grey and black bezel offers a more subtle and elegant alternative to the brighter colorways in the professional line. Enthusiasts frequently praise the return of yellow gold to the GMT family and the inclusion of the Jubilee bracelet, which is noted for its exceptional wearability and “vintage” appeal. While the watch is celebrated for its mechanical ingenuity and refined aesthetics, some critics point out that the grey segment of the bezel can be difficult to distinguish from the black half in certain lighting conditions. Overall, it is regarded as a versatile and handsome addition to the Rolex catalog that appeals to both collectors and frequent travelers.
